Presentation Transcript

  1. Glycol Pumps Circulation Rate: 3 to 450 gph Operating Pressure: 100 to 2000 psi

  2. A pump used for circulating glycol within a dehydration system. A pump used to circulate amine within a desulphurizer system. What is a Glycol Pump?

  3. No auxiliary power required Eliminates need for level control and dump valve at absorber Low gas consumption Completely sealed system prevents glycol loss Only two moving assemblies Hydraulic “cushioned” check valves with removable seats of hardened stainless steel Circulation Rates: SC Series 8 - 200 gph PV Series 3 - 450 gph Features

  4. Natural Gas Dehydrator Contactor Tower Glycol Cooler Reboiler Dry Gas Outlet Inlet Scrubber Wet Gas Inlet Surge Tank High Pressure Filter Excess Separated Gas Outlet Condensate Outlet Three Phase Gas, Glycol & Condensate Separator Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure) Condensate Outlet

  5. Natural Gas Dehydrator Dry Gas Out Dry glycol Reboiler Absorber (Contactor) Wet glycol Wet Gas In Pump Dry glycol Heat exchanger surge tank Wet glycol

  6. Natural Gas Dehydrator Dry Gas Out Dry glycol Reboiler Absorber (Contactor) Wet Gas In Wet glycol Wet gas enters the bottom of the absorber. Pump Dry glycol Heat exchanger surge tank Wet glycol

  7. Natural Gas Dehydrator Dry glycol enters from the top of the Absorber Tower. Dry glycol Reboiler Absorber (Contactor) Wet glycol Wet Gas In Pump Dry glycol Heat exchanger surge tank Wet glycol

  8. Natural Gas Dehydrator Dry gas exits from the top of the Absorber. Dry Gas Out Dry glycol Reboiler Absorber (Contactor) DRY glycol falls through the bubble caps, as the WET gas travels up through the bubble caps. Wet glycol Wet Gas In Pump High pressure wet glycol goes to Glycol Pump. Dry glycol Heat exchanger surge tank Wet glycol

  9. Natural Gas Dehydrator Dry Gas Out Dry glycol Low pressure WET glycol goes to the reboiler to be dehydrated. Reboiler Absorber (Contactor) Wet Gas In Wet glycol Pump Dry glycol Heat exchanger surge tank Wet glycol

  10. Piston ready to move to the right Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  11. Piston on its way to the right Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  12. Piston ring contacts actuator Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  13. Actuator moves ‘D’ slide to the right Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  14. ‘D’ slide shifts ports Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  15. High pressure shifts pilot piston Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  16. Reversal of flow shifts check valves Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure) Animation

  17. Loss of fluid circulation Runaway pump Hammering sound Pump skips Pump runs until normal temp. is reached Erratic pump speed Pump stalls Leaking check valves Valve body seal Dart seal Piston, piston rod seals Suction Lines too small Traps in wet glycol power piping send alternate slugs of glycol-then gas Plugged lines in dehy system Swollen O-rings Plugged passages in pump Blocked check valve Loose actuator Pump Trouble Shooting
